GEDmatch
A cross-company DNA matching workspace for genetic genealogy research.
GEDmatch lets users upload raw DNA files from major consumer testing companies and compare results against a large shared database. Its tools support match finding, one-to-one DNA comparisons, admixture analysis, GEDCOM-based ancestor research, clustering, and other workflows used by genetic genealogists.
Why it stands out
- Combines matches from multiple DNA testing companies instead of keeping users inside one vendor’s database.
- Large public comparison pool, with the page citing more than 1.5 million profiles and 50M+ people in GEDCOMs.
- Offers specialized genetic-genealogy utilities beyond basic match lists, including clustering and superkits.
- Provides upload guidance for several major testing providers, reducing friction for first-time users.
Good to know
- Requires taking a DNA test elsewhere and downloading a compatible raw DNA data file before using the main tools.
- Results depend on who has chosen to upload data to GEDmatch, so coverage varies by family line, region, and community.
- Users are handling sensitive genetic information and should review the site’s privacy, security, and law-enforcement-related policies before uploading.
- The page emphasizes autosomal DNA comparison, so it may not replace tools focused on every DNA test type or record-based genealogy workflow.

Genetic genealogists, adoptees, and family historians can compare DNA matches across testing-company boundaries. Upload an Ancestry, 23andMe, FamilyTreeDNA, MyHeritage, Living DNA, or similar raw data file for broader matching. Use one-to-one comparisons to confirm how much DNA two people share before reaching out. Explore ethnicity estimates, clustering, and GEDCOM connections to support family-tree research.
Raw DNA upload support from major testing services; One-to-Many and One-to-One autosomal comparison tools; admixture and heritage analysis; GEDCOM-based family-tree research; clustering and “superkit” utilities; educational guides and videos for beginner through advanced users.

DNA tests for tracing family lines across autosomal, Y-DNA, and mtDNA.
Genealogy & family-history researchFamilyTreeDNA sells consumer DNA tests aimed at ancestry and genealogy research, including autosomal matching, direct paternal-line Y-DNA, and direct maternal-line mtDNA. Results can be used to find genetic relatives, view ethnicity and haplogroup information, and connect DNA evidence with family-tree work through partner integrations and group projects.

Genealogy & family-history researchDNA Painter helps genealogists interpret DNA match information through chromosome maps, relationship calculators, and family-tree-based probability tools. Users can map shared DNA segments to known ancestors, explore possible relationships from shared centimorgan amounts, and build visual pages for direct ancestors.
